To dll/whom tzt/may concern: i

. A Be it known that I, LBERT I). LEE, a citizen of the UnitedStates,residing at Chicago, in the county of Cook and State of Illinois, haveinventeda. certain newA and useful Improvement in Dumping Vehicles, ofVwhich the following is a I'ull, clear, concise, and exact description,reference being l had to 'thefaccompanying drawings, forming apartof'thisspecicatiom l i f i.

YIy. invention relatesvto dulnping vehicles and more particularly to adumping vehicle which lis provided with a hopper adapted to roll fromchargereceiving'poslparent from the,

' have .disclosed one tion .toward the rear end of the vehicle anddischarge its load over the upper end of the hopper. Y 1 n It is anobject oirmy invention to provide 1a dumping Vvehiclejofv the character.set forth, y

whichhas a hopper of; large capacity, which hopper is provided with 'asubstantial beanv ing V,portion in contactwith the :trame ofthe.

vehicle sowas toprovide a rigid and sub- A stantial support for thehopper.

Itis a further objectlot the invention to provide a drop. frame vehiclehaving a hopper positioned the .frame which hopper is adaptedto rollalong the frame and discharge its load lbe'- yondthe rear end oftheframe. y

,It isa further objectof the lnvention'vto provide means for securelymaintaining the hopper in its charge receiving. position which vcontrolthe movements ofthe hopper whilev it is rolling toward its 'dischargeposition. Insome cases it may be desired to discharge only aportion ofthe load in the-hopper. In, such 'cases means are necessary to preventthe hopperffrom rolling completely to its discharge position. Thecontrolling means l. havedevised enf ables me to eliectively control themove-l mentslof the hopper and-to hold it in any de sired position.

rOther objects'ofthe inventionwill be ap device .disclosed in thedrawings wherein `I present time. However, itis to be under-. stood thatby this speciication and the ac* comp'anying drawings VI do not, intendto limit'myselfto the specific construction disclosed las modiicationsofthe speciicconstruction'may be required in the manufaclon the lowerportion of' detailedV description of the; Ving provided ln a form of myinvention, Ywhich form is the best known to me at'the, A`

Fig; 4 is asection takenrfromline 4-4 of Figti' is `a section taken venline 5,-5 of Fig.V 3.

In the drawings I have vdisclosed a trailer frame work .comprisingside'. members 10 which have? raisedy vportions-11 at their `for`v wardends andfdrop,or-,depressed portions 12 at theirrear ends. Thesidemembers 10 are .preferably formed from the single 4plateY soV whichis cutto the desired shape and is thenV Y reinforcedA along its edges bymeans of .angle hars which are securelyriveted thereto as shown inV mycopending application, `Serial 293,202, of-which this, case is adivision. The sidemembers 10 are securely and rigidly connected togetherby means of channel cross members 13,14, 15, 16,117 Iand 18. -Atftheforward corners of the frame work thus Jformed I provide brace plates.19 Aand 20.

The construction just .described provides a rigid rectangular frameworkuponl which the hopper, later to be described, ismounted.

f Extending across the members 1,3 and I forms ka .rigid support for aking bolt 22 which is adapted to engagea suitable .open-- a, front truckstructure '24.' This truck The front axle is pro.n

l,Eiiaiialiiig longitudinally Q'i'filie vehicle :trame work andrigidlyfconnected to the cross members 1A and. 15 are channel members28, 29 and 30..-which channel members,

,thera-me work between .Y l14:` is an I-bealn 21 vwhich turn table.23.,c`arried by Y supporting means together with the side member l0shown near ,the bottom of Fig. 2, form suitable and rig'id for thehoppery controlling mechanism which will be describedlater.

Between the raised portion ll and the depressed portion l2 of the framework there is a downwardly inclined surface 3l against which the frontwall of t-he hopper will rest when the hopper is 'in normal position.rIhe depressed portion l2 is provided with a 'horizontal bearing portion32 and beyond this bearing portion is an inclined portion 33 down whichthe hopper may roll to its discharge position. At the end of theinclined portion '33 I provide hoolr members 34 which provide pivotmeans for the hopper as it swings to its discharge position.

'Ihe hopper which rests upon the depressed portion of the iframe workcomprises vertical side walls 35, an inclined front wall 36, a flat andsubstantially horizontal bottom wall 37 and an inclined rear wall-38. Onthe outside of thehopper I provide bearing rails which have inclinedportions 39 extending along the iront wall 36 of the hopper. The railshave horizontal portions 40 which are secured to the Hat bottomportion37 of the hopper, and beyond these portions the rails are curved asshown at 4l in the drawings. These curvedV portions of the rails areadapted to engage the inclined runways 33 so that the hopper may rolldown the'runways with a smooth rolling movement. Beyond the curvedsections 4l are straight portions 42 of the rail which strengthen theinclinedrear walls 38 of the hopper and form suitable means to which thehopper holding mechanism may be secured. Adjacent the meeting point ofthe curved sections 4l and the straight portions 42 the hopper isprovided with pivot pins 43 which are adapted to engage the hook members34 l when the hopper reaches the end of the runways' 33. After the pins43 have engaged the hook members 34 the hopper will swing around thepins as pivots until the load is completely discharged. This swingingmovement is limited by the controlling mechanism which will later bedescribed. At the krear end of the hopper I provide a spreadingattachment 44 which may be used for regulating the discharge of thehoppercontents over the rear edge of the hopper. ThisV arrangement isnecessary when thejhopper is used as aspreading device. l As thisfeature forms no part of the present invention it is not disclosed indetail.

The rear end of the frame work is Vprovided with longitudinallyextending niembers 45 which are suitably secured to the cross channels17 and i8 as shown in Fig. 2. The members 45 constitute suitable meansto which springs46 and 47 may be secured. These springs extendtransversely of the vehicle as shownin the drawings and their ends aresuitably attached to the rear axle 48 which axle in turn carries thewheels 49. While this method of attaching the rear wheels has beendisclosed in the drawings, it will be apparent that other means and ar`rangements of springs may be used if desired. Y

In order to maintain the hopper in its normal charge receiving positionand to control its movements during the dumping operation the followingmechanism is used. Secured to the rear cross member 18 are brackets 50which brackets provide suitable means for pivotally supporting togglemembers 5l. There are two of these toggle mein-` bers as will be clearfrom Fig. 2, one positioned adjacent each side of'lthe frame. Thesetoggle members 5l extend upwardly and have their upper ends pivotallysecured to a pivot rod 52. PivotallyV connected at 53 to bracketscarried by the hopper and associated with the rail portions'42 are uppertoggle members 54 which have their lower ends pivotally connected to therod 52. The members 5l and 54 provide a toggle mechanism which is shownin 'its extended position in Fig. lof the drawings. rod 52 is permittedto move to the right in Fig. l the toggle mechanism is collapsed landthe hopper is permitted to roll down Ythe members from swinging pasttheir normal -position shown in Fig. l I provide extensions 55 onthetoggle members54'which extensions are provided with fingers 56adapted to engage the lower toggle members 5l as shown 'in Fig. l. Thelingers 56 prevent the toggle members fromv swinging beyond their normalposition shown inF ig. 1. j Pivotally connected to the rod l52 adjacenteach of the toggle members is a link 57v and the links 57 are connectedby means of a rod or bail member 58 which bail has secured thereto oneend of a cable 59. This cable extends forwardly over a pulley 60 carriedby the cross memberl? and then passes under a second pulley 61 suitablyconnected tothe cross member 16. From this point the'cabler passesupwardly and over pulley 62 carried by the hopper adjacent the upperedge of the front wall 36, and then passes downwardly and around awinding drum 63. which is rigidly secured to a stubv shaft 64 as will bemore apparent from Fig. 3 of the drawings. The stub shaft 64 has itsbearings in the longitudinally extending The drum 63 has an enlarged hubportion When the i runways 33j In orderto prevent the toggle members 28and 29.

69 is in alignment with-.the shaft6t'as will be'. clear fromFig. 3' ofthe drawings. 'In order to connect and disconnect the clutch element. 68from the element-67 l provide a clutch, operatingmember .7l which issupported in brackets '72 and 7 3 carried -by the frame work. The clutchoperating member is .provided with a handler; by means of which it maybe easily operated. When the handle Tl is-pulled outwardly it serves todisconnect the clutch element 68 yfrom Vthe element 67. lVhen the handleis moved inwardly the reverse operation takes place.

Keyed yto the shaft 69 by means of the-key 7 5 is a'bevel gear 76 whichmeshes with aV bevel ygear 77A secured to the shaft Swhich vshaft ispositioned at right .angles to the shaft 69. lAlso secured to the shaft78 is a worm 7 9 whichmeshes with a worin'wheel The worm and worm wheelaresuitably enclosed in a housing 82 Vwhich forms bearings for ltheinner end of the shaft 81 Vas shown in Fig".V t. The

Yshaft 8l extends through aside member 10 and its outer end is Vprovidedwith a squared shank Si?, to which Va crank or other operating membei1may be attached for :control-l ling the movements of theliopper. Thehousing 82 referred tov isV .cast in. two parts as :shown lin Fig.; 4ofthe drawings and these parts are held together bybolts or rivets asshown vin Fig.l4. The clutch voperating member 71 hasitsinnerfend,turned downwardly as shown at 83 in Fig. 3 and this endis'fforked in order thatv it may engage a'groove inthe. clutch elementV68 as shown in Fig. 3. 'Y Y rl`he raised portion `1l of theframe worksupports an auxiliary hoppervStiwhich hop-V per may be used for anydesired Vpurpose but is preferably used for carrying tools,

etc., which are 'used'on the :work Vfor which" the vehicle is intended.

From what has been described abovethe construction of my device will beapparent. The operation will also be apparent from thepreceding.descriptions, Vbut a brief description of the operation willbe given here. Then the hopper is loaded it has a tendency to rolldown-the runway 33 toward its discharge position. p This movement ,isprevented by the toggle members 51 and 54 which are maintained in theposition shown inV Fig. l by means ofthe cable 59. When it is desired todischarge the/load from the hopper the operator places a crank or otheroperating member on the squared shankSQ` of the shaft 81. The shaft 8l`and worm wheel 8() will then be rotated inthe proper direction. Thiswill permit the wormV 79 to turn under the weight of the hopper. It willbe understood that the hopperdue to its shape and the load containedtherein' exerts a constant pull on the cable 59. As

-the 'shaft 8l is turned the worm79fis released and the gears 76 and vT7and the shafts 64 and 69 are turned yunder the actionV of the hopperdrawing 'envthe cable-59.

If it is desiredlto permit the hopper to roll atonce to its completedi's'chargingposition the operator will .pull out on the ha1`1dle'74 todisconnect the clutch elementf68 Vfrom the clutch element 67 This freesVVthe-drumv c ment ofthe hopper..` `When Ythe clutche-le. y' Y so yments are left in engagement as shown in Fig. 3, .the hopper maybevstoppedvin any desiredposition on the-runways `33.Y The worm 79 andworm wheel 8Oy constitutera locking connection so that the'sha'ft 8l'cannot" rotate due to the .pull 'on the cable `59 and the hopper canroll'down the'runiways only when the shaft V8.1 is rotated by vtheoperator.
